Comparison Between Industrial Classification Systems in Freight Trip Generation Modeling

This paper compares two different industry classification systems used in freight trip generation (FTG) modeling, i.e. Standard Industrial Classification (SIC) and the North American Industry Classifications System (NAICS). The analysis focuses on the difference in the types of models generated and the models' ability to replicate the input data by industry sectors. The models are estimated using Ordinary Least Square (OLS) and Multiple Classification Analysis (MCA) techniques. The analysis uses two samples from the New York metropolitan area, receivers and carriers, to determine which of the two industrial classification systems provides better results when used in FTG modeling of freight attraction and production.
